The A1301 and A1302 ratiometric, linear Hall-effect sensors in a SOT23 package are rated for operation to 150 degrees. The A1301 and A1302 ratiometric, linear Hall-effect sensors in a SOT23 ...

It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor ...

[John Crombie] had a crack at building one using linear Hall effect sensors and magnets as the ... [John] utilises the Arduino pro micro for its copious analog inputs and USB functionality.
